A pickup truck has a five liter four stroke cycle, v6, Si engine operating at 2400 rpm. The compression ratio rc=10.2:1, the volumetric efficiency etav=0.91, and the bore and stroke are related as stroke S=0.92 B Calculate: (a) stroke length. (cm) (b) average piston speed. (m/sec) (c) clearance volume of one cylinder. (cm^3) (d) air flow rate into engine. (kg/sec)
